nnvIcE FOB-SIGNALING CHANGES or nnivriis In nuir'oluoisinns.

Be itlnrown that'l, EVALD 'HEBEL, residing at Copenhagen, Denmark, haveiinvented' certain newan'd useful Improvements in Devices for Signaii ng Changes or Driving" this by a signal'uy :While such Sig-- nals may be iven observed with reason able ease, when'given from an entirely open earria e at any rate during day-time" this mode" of signaling,- whieh'the driver in certain eounjtriesisobliged to perform,

is xtremely inconvenient when the driver sits inside are closed? or merely coveredriage, and at night an signaling-of the kind'hfe referred to will be almost impossibl-e' to observe. It'liastherefore been proposed to provide wings, maybe in connectionwith other signaling' devices at conspicuous points of the carriage andto oper ate these devices from the drivers .seat.

The present invention relates to a device adapted to operate such signals in" extremely easy manner, the said'deviee being entirely reliable and easy to readjust. The signals will be easy to observe from ahead as well as from behind, and in day-time as'well as at night.

The invention is shown on the drawing,

Fig. 1. showing, in front elevation, the operating box with the operating handle,

Fig. 2. the same in section along the line .A-A of Fig. 3,

Fig. 3. the same in section along the line B'-B of Fig. 2, a v

Fig. 4:, shows one of the signal arms, partly in section.

Fig. 5. is a detail.

The device consists of a case 1 containing the power transmitting members, and two or maybe several wings serving as signals, and Bowden cables connecting the case and the said wings.

The case 1, which is disposed in front of the driver on the dash-board or at other suitable place, contains a horizontal shaft 2 adapted to be turned in bearings 3 by means of a handle 4 with pointer 5. The shaft 2 is provided with a square disc 6 disposed between two springs 7 in such a manner that the shaft may occupy only point of theicarri'a'ge.

' which a four positions. On the shaft there are prof vided, .furthermore,-- a couple of' eccentric-sf 8' and gco-operating with the arms ltl'a nd 11,- which are .pivoted about pins 1-2,-"and are fittedat-top: with segments 13 forfat tac'h'me'ntiof each of the ca bles--14- and 15' passing, througlrfiexible tubes 16, v17, each to its wingdisposed at some conspicuous The right-hand wing is shown on Fig; 4.

An arm 18 with a lug 19 for attachment to the carriage is fitted at' top with a head 20j'slotted for the inner end of the wing 21-, which is pivoted about a pin The fieXi bl'e tube 16 extended u p to the head 20,

and the end of the cable 141; enclosed in the tube is screwed onto the top portion 23of the curved-end of the wing. I Q V I The wing will normally hang dowir verti o 'a llyor nearly vertically in the position indicated by: a dot and dashed-line inFigr If the carriage is to betu r'ned to the" a manner that the pointer 5" points to the right on the front-face of the case i, on

vided.

When the handle is tu d, the ecce tric 9 will be turned so far that will swingthe arm-10 to the'left, Fig. 2',-'and th*e camera.

will thereby be tightened causing the wing '21 to be swung up into the position shown in Fig. 4, and it ought to be noted that when the handle 4 occupies the position shown in. Fig. 1, none of the two wings will be raised.

suitable inscription may be pro:

side, the other eccentric 8 will swing the other arm 11 sideways and, exactly as described above, swing the other wing up.

If the handle is turned 180 from the position shown on the drawing, the two eccentrics will have turned both of the arms 10 covered by coloured glasses, so that for instance the glasses'in the right-handlans tern may be green, tern red.

By way of a knife-switch consisting of a and in the left-hand lanpair of springs and a knife 26 provided i on the inner end of 'the wing, the lamp is connected in series with another lamp 24 in; the case 1. This last mentioned lamp may be t placed behind a correspondingly coloured glass in the front face of the easel.

The wiring diagram proper is not shown on the drawing for the reason that it forms I no part of thepresent invention, but, it will easily-be understood that when the handle 4, on Fig. l, is turned for instance to the left and, consequently theright'hand wing is raised, the knife 26 of the 'wing'will come into contact with the springs 25 and, thereby close the circuit in such a manner that not only the lamp provided above this wing will several manners without the scope of the invention being passed.

' Havlng now partlcularly described and ascertained the nature of my said invention,

'and in what manner the same is to be performed, I- declare that what I claim is '1. A signaling device of the character det scribed for use on automobiles, comprising a case, a shaft mounted in the case, a handle on the shaft, swinging arms mounted in the case, Bowden cables connecting the said arms to signaling members, and eccentric discs mounted on the shaft and adapted tr) swing the said arms to operate the said signal members. r V

2. A signaling device of the character de scribed for use on automobiles, comprising a case, a shaft mounted in the case, a handle onthe shaft, swinging arms mounted in the case, segments provided on the free ends of the said arms, Bowden cables connectin the said segments with signal members, an eccentric discs mounted on the shaft-fand adapted to swing the said arms tooperate the said signal members. J

3. A signaling device of the character described for use on automobiles, comprising a case,'a shaftmountedin'the case, a handle on the shaft, a pair of swingingarms pivotally mounted one at each side of the shaft, a segment on the free end oft-each arm, a cable connecting each segment with a signal member, and an eccentricdisc mounted on the shaft and engaging each of said arms to swing the same and operate the signal.

c, 4. A signaling device of the character del scribed for use on'automobiles, comprising a case, ashaft mounted in the case, a handle on the; shaft, spring means engaging the shaft to retain same in any adj usted position,

swinging-arms mounted in the case, Bowden 7 cables connecting the said'arms to signaling a members, and eccentric discs mounted on the shaft and adapted to swing the said arms to operate the said signal'members.

. In testimony whereof I afiix my signature 7 in presence of two witnesses.
